dbtp

<p>Parameters for linear regression models to estimate double bark thickness
according to species, diameter over bark and stem part.</p>

datasets

Providing new german-wide 'TapeR' Models and functions for their
evaluation. Included are the most common tree species in Germany (Norway
spruce, Scots pine, European larch, Douglas fir, Silver fir as well as
European beech, Common/Sessile oak and Red oak). Many other species are mapped
to them so that 36 tree species / groups can be processed. Single trees are
defined by species code, one or multiple diameters in arbitrary measuring
height and tree height. The functions then provide information on diameters
along the stem, bark thickness, height of diameters, volume of the total or
parts of the trunk and total and component above-ground biomass. It is also
possible to calculate assortments from the taper curves. For diameter and
volume estimation, uncertainty information is given.
